Try Before You Buy...

This goes a long way in helping to avoid the silly purchases of things you rarely or never use. Before you buy something, especially items with big price tags, borrow one, rent one or try one out before you plunk down the cash. If you are bored with it, or determine that it truly is not something you need before you buy it (and you will be on a certain percentage of items) you will definitely be bored with it, or find it not that necessary, after!
